The bottom half of my defroster doesn't work. The top half works great though.

I think I may have loosened a connection while installing my sub woofer in the rear deck a few months ago. Where should I be looking to check the connection? The C pillar on which side and about where should I be looking. I would normally take it all apart but its cold out and I don't want this to take more time then it needs to.
